Step 1
The horizontal velocity of the object remains constant throughout the time. It is 73.1 m/s to the right at all times. This is because there are no horizontal forces acting on the object after it has been launched. Show more…

A projectile is shot from the edge of a cliff 2.57 x 10^-16Em above the ground level with an initial speed of 4.32 Km/min at an angle of 66.0^0 with the horozontal. (a) Determine the time taken by the projectile to hit the ground. (b) The range of the projectile from the base of the cliff. At a certain point K 6.5 x 10^-2 Km from the ground, find (c) the vertical and horizontal components of its velocity, (d) the magnitude of the velocity, (e) the angle made by the velocity vector with the horizontal, (f) the maximum height above the cliff top reached by the projectile. Select one: a. a: 16.6 s, b: 477 m, c: Vkx=29.3 m/s; Vky= 88.9 m/s, d: Vk= 95.0 m/s, e: 72.0^0, f: 230 m b. a: 16.6 s, b: 486 m, c: Vkx=29.3 m/s; Vky= 90.0 m/s, d: Vk= 94.6 m/s, e: 72.0^0, f: 221 m c. a: 15.7 s, b: 487 m, c: Vkx= 30.1m/s; Vky= 99.9 m/s, d: Vk= 92.6 m/s, e: 72.0^0, f: 202 m d. a: 14.3 s, b: 478 m, c: Vkx=27.7 m/s; Vky= 87.0 m/s, d: Vk= 94.6 m/s, e: 71.0^0, f: 263 m

The drawing shows projectile motion at three points along the trajectory. The speeds at the points are v1, v2, and v3. Assume there is no air resistance and rank the speeds, largest to smallest. (Note that the symbol ">" means "greater than".) A. v1 > v2 > v3 B. v2 > v1 > v3 C. v1 > v3 > v2 D. v2 > v3 > v1 E. v3 > v2 > v1

Curvilinear Motion - Rectangular Coordinates (Projectile Motions) 3. A cannon ball is fired from point A with a horizontal muzzle velocity of 120 m/s, as indicated in figure. If the cannon is located at an elevation of 60 m above the ground, determine the time for the cannon ball to strike the ground and the range R. Ans. 3.5 s, 420 m
